To all whom it may concern: u

Be it known that I, FRANK A. DECKER, a s acing means, vand holes citizen of the United States,` andare'sident of p ate body Philadelphia, in the'county of Philadelphia through.l

have inventedi in Battery Elements, of whichthefollowing is a specification.

In the preferred elementlca'rbo'n is brought l with-the current accumulation at the -'severa to a form, preferably by molding and baking elevations.

.having a corrugated or ine In the assembled construction dente body with borders and transverse Fig. 4 the cell lenvelop 1.1v has the ribs reinforcing it, the top ofthe plate being supported 'on the bottom thereof enlarged either by ilanging orgradually bottoms of the cups or compartments 13 thickening and having means for engaging a lresting inthe Seats binding-screw securely therein.

In the accompanying drawings, Figure 1 represents a face View of a plate made in accordance with my invention. Fig. 2 repre- Sent-s a top view thereof with a part shown in section. Fig. 3 represents a sectional view taken on the line 3 3 ofFig. 1. Fig. 4 represents an end view of the plates or electrodes thecell, the wall of which has been broken away;- and Fig.'- 5 is a perspective View of a section of the top of a plate having -a modified construc-A tion.

As shown in Figs. 1 to 4, inclusive, of the drawings, theinvention is a.carbonplate having the body corruga'tions 1 crossed by the intersecting reinforcing ribs or stays 2, with the bottom border 3, the side borders 4, and 'the top flange or anges 5 thereon, gasvens 5 being provided in the lower parts of the flanges.- Set across the langed top of the plate is a holding device 6, preferably of metal, with a thread therein to form a nut, cast or otherwise, inserted in the seat prorugations'.l g l vided therefor in the to ofthe plate. A '3. AVbattery-plate of molded and baked threaded hole 7, dispose lengthwise in the carbon having a nut embedded therein, a top of the plate and extending-through the hole insaid element passing through said nut, nut 6 and the greater part ofth'ewidth of the and a metal screw in said hole engaging said plate, receives a long binding-screw 8, which vnut and element. 1s thus providedwith an effective electrical 4. and /iirI/n mechanical connection with the shown in and dividing the cell into-compartments 14', tapering fremthe bottom tothe top. In the compartment-sl 14 are. the carbon plates '15 15', respectively" supported by" their of the cups and covering the compartments exterior thereto. The yvents 5 in the'iianges .permit the escape of gas from the ,compartments otherwise covered. The plates bear against the faces ofthe cups, while 'the plate-bottoms engage the bridge 12, by which the plates are held. .Having described my 1.
